Title: Analog electronic clock
IPC: G04C10/00
Filed: 1992-03-17
Abstract: PURPOSE:To eliminate an erroneous recognition and improve reliability by setting voltage setting values A and B to be higher than an actuation stop voltage of a motor and B>A in two voltage detection circuits of a secondary power supply. CONSTITUTION:Vibration of an oscillation circuit 4 allows 1Hz motor drive pulses 01 and 02 to be output from a clock control circuit 5, which are output alternately every 1sec from motor drivers 7 and 8 through AND gates 13 and 14, thus driving a coil 9. On the other hand, voltage detection circuits A 11 and B 12 have detection setting values A and B whose relation is expressed by A<B. When an output signal CNT level of a motor output control circuit 6 is at a voltage Vcc side, the pulses 01 and 02 are output to the drivers 7 and 8, thus activating the clock. At this time, the clock is left and in non-generation state, the voltage Vcc is gradually reduced and becomes lower than the setting value A and then the CNT level reaches a Gnd side, thus preventing the pulses 01 and 02 from being output and enabling the clock to be stopped. A battery 3 recovers voltage gradually owing to reduction in load current and is further increased owing to operation of a generator and exceeds the setting value B. At this time, the CNT level reaches the voltage Vcc side and the clock is in operation state again.

Title: Laser ignition device
Inventor: NODA SHOHEI
IPC: F02P23/04
Filed: 1993-02-26
Abstract: PURPOSE:To ensure laser ignition by cleaning an optical window by spraying liquid which is the same as fuel on the optical window which leads laser beam immediately after the compression process of a liquid fuel engine is started in an ignition device of the engine. CONSTITUTION:When a signal 14 at the bottom dead point of a piston 15 is input, a solenoid valve 10 is opened to feed fuel in a fuel tank 8 under pressure into a nozzle 11 for cleaning by a pump 9 for cleaning. Thus, fuel becomes atomization for cleaning (alternate long and short dash line) from the nozzle 11 and is sprayed on an end face of an optical window guide 3 to clean the end face of the optical window glass. Then, a fuel nozzle 6 jets fuel atomization 7 in synchronization with crank angle, and in synchronization with this, laser beam 1 passes the optical window glass 3 via a laser beam guide 4 and a lens 2 to irradiate the laser beam 1 from the end face. Thus, as the optical window glass is cleaned by fuel every time before laser is irradiated, attenuation of laser due to dirt on the optical window glass does not occur, and laser ignition is possible at all times.

Filed: 1999-03-09
Abstract: PROBLEM TO BE SOLVED: To simply correct color smear, even when a color image reader reads an image while adjusting the focus in matching with a face of an original, when reading a three-dimensional object such as a book original. SOLUTION: When focus is adjusted and a lens is moved in a direction of an optical axis, a projection magnification is calculated for each line of R, G, B sensors on the basis of a reference line 31 on an original platen 13. When each magnification is different with each sensor reading an image at the same object position, magnification of the image read by other sensors is corrected in matching with the projection magnification of one of the sensors. Thus, even when the image of a three-dimensional object such as a hook and a file is read, color smear can properly be corrected.
